How to Install an Exhaust Hood for a Gas Stove

If you have a gas stove you will definitely need an exhaust hood. This is a job that can be done by a do it yourself homeowner with some effort. Natural gas gives off fumes that are dangerous to people and when in use the vent hood fan should be running to draw the fumes as well as smoke and grease out of your kitchen.

Step 1: Prepare Area for Vent Hood

Whether you are replacing or installing a new range hood you will need the same tools. A vent hood is a large and cumbersome appliance so be sure that you secure a friend to help you with the project or assemble a frame to hold the vent hood in place when you secure it to the ceiling or bottom of the cabinet.

Step 2: Choosing the Range Exhaust Hood

The instructions here are dependent on the vent duct already being in place. If you do not have ventilating duct work already then look at the how-to "How to Ventilate a Range Hood." When you are choosing the vent hood make sure to check the CFMs. CFM simply means cubic feet per minute or how much air the fan is able to move in a minute's time.  Whatever your square footage is on your room, double it and that will determine the CFMs you need. For example if you have 100 square foot kitchen then you will need a vent hood with 200 CFMs. You also need to choose the size of your vent hood. There are different widths and depths available to suit your range and your space limitations. Measure your space and get the proper fit before investing in the range hood. Of course there are many colors to choose from and also a brushed stainless steel option.  

Step 3:  Installing the Range Exhaust Hood

Remove the filter, fan, light and electrical housing from the vent hood. Punch out the hole for the electrical cord to pass through. Run the electrical cable through the hole and secure it to hook to the electric motor later. Align the hood with the vent duct that is in the ceiling or the wall. Cover the other hole in the hood that you are not needing for the vent duct. Install a cable clamp to the hole you knocked out. Screw the hood into the ceiling or bottom of the cabinet where it is to go. Use the wood frame to hold the hood in place while you secure it.

Step 4:  Re-assembling the Exhaust Hood

Install the fan, light cover and filter. Connect the wires to their coordinating wires on the power cord, and cover each with a wire nut. Wrap the cables neatly and cover the joints with the electrical housing cover. Plug the power cord into the outlet and turn it on to ensure that the light and fan both work.
